From https://about.usps.com/newsroom/local-releases/nc/2025/1030-usps-provides-sneak-peek-at-2026-stamps.htm:
Bruce Lee
As the first Asian leading man in American film, Chinese American
martial artist, actor and filmmaker Bruce Lee (1940-1973) captivated
audiences with his skill, charisma and screen presence and inspired
generations of fans. The stamp artwork by Kam Mak features a painting of
Lee executing his iconic flying kick. It is set against what Antonio
Alcalá, the art director for USPS who designed the stamp, calls “a
calligraphic yellow brushstroke,” a reference to the iconic yellow
tracksuit Lee wore in “Game of Death.” On the right side of the stamp,
BRUCE LEE and USA FOREVER are printed vertically and angled to appear as
if Lee’s kick were breaking them in half.
Nothing against the Post Office--which is doing a cool thing--but I still do think Sessue Hayakawa was the first Asian leading man in American film.
